“Dog Whisperer” Cesar Millan has a special bond with dogs, but it seems he doesn’t share the same closeness with pigs. The 46-year-old is under investigation for possible animal cruelty following an incident while filming for his TV show Cesar 911, which airs on the Nat Geo WILD channel. Cesar Millan used a pig to train an aggressive dog that had previously attacked two other pigs. That dog then reportedly bit off part of the pig’s ear during filming.

A clip of the show was posted to YouTube and shows a pig being restrained by an assistant on the show. Millan has let the dog off the leash, and when he hears the pig squeal, runs over and attacks it.

Investigators were not able to find out the state of the injured pig as Millan was out of town. In the segment, the dog stayed calm for about a second before bolting to chase the pigs. He then ignored one of Millan’s standard commands to stay and continued to run free, nearly chewing the animal’s ear off before he could be stopped.

 

Fans heard the pig's squeals and were furious.

Millan has 24 hours to respond to the investigation, animal welfare officials told the station.

 

Millan struggled to restrain the dog after the attack.

However National Geographic Wild says viewers “did not see or understand the context of the encounter.” The channel said Cesar Millan took necessary precautions with Simon before the mauling.
